Description

Technical Field

[0001] This utility model relates to the technical field of insulated glass, specifically to a type of airtight insulated glass. Background Technology

[0002] Insulating glass, a new type of building material integrating high-efficiency heat insulation, sound insulation, and energy saving, has become a core component in modern architecture, transportation, and home appliances since its inception. Its air-layer structure formed by two or more panes of glass reduces building energy consumption while effectively blocking external noise, significantly improving living comfort. In the construction field, insulating glass is widely used in curtain walls, doors and windows, skylights, and other applications. With continuous technological advancements and accelerated urbanization, the application of insulating glass is becoming increasingly widespread.

[0003] Although the structure of insulated glass is quite simple, during use, especially in low-temperature environments, fogging or condensation frequently occurs inside the air gap, and in severe cases, water can accumulate. This significantly affects the thermal insulation performance and visual appeal of the insulated glass, and drastically shortens its lifespan. This phenomenon is closely related to the sealing materials and sealing structure of the insulated glass. Therefore, replacing the sealing materials and improving the sealing structure of insulated glass are key to improving its quality. Utility Model Content

[0004] The present invention aims to provide a sealed insulated glass unit to solve the technical problem that fogging, condensation, and water retention often occur inside the insulated glass unit in low-temperature and cold environments, which greatly affects the thermal insulation performance and visual effect of the insulated glass unit and significantly shortens its service life.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] 1) A type of sealed insulated glass, comprising two glass plates with a certain gap between them, the gap being filled with an inert gas, and a long strip spacer provided on the edge of the two glass plates within the gap. The two ends of the spacer are respectively bonded to the two glass plates with butyl adhesive. A silicone sealant block is connected to the side of the spacer away from the inert gas, and the two ends of the silicone sealant block are bonded to the two glass plates with butyl adhesive. There is a gap filled with butyl adhesive between the silicone sealant block and the spacer.

[0007] In this invention, the two glass panels are made of the same material and are the same size. The two glass panels are arranged in parallel with their edges aligned to form a gap in the middle. The gap is filled with argon gas, which has low thermal conductivity and can effectively prevent heat from passing through the glass, reduce heat exchange between the indoor and outdoor areas, and maintain a relatively stable temperature between the indoor and outdoor areas. In addition, the inert gas can block the transmission of sound to a certain extent, thereby improving the sound insulation performance of the insulated glass. After filling the insulated glass with inert gas, its internal pressure is more stable, which can reduce the pressure difference between the inside and outside of the glass caused by factors such as temperature changes, thereby reducing the possibility of spontaneous breakage of the insulated glass.

[0008] Butyl sealant possesses excellent airtightness and watertightness. By bonding the spacer strip, silicone sealant block, and two glass plates with butyl sealant, and simultaneously filling the gap between the silicone sealant block and the spacer strip, a multi-layered sealing structure is formed. This greatly reduces the possibility of external air and moisture entering the gap between the two glass plates, ensuring that inert gas is not easily leaked. This effectively maintains the sealing state of the insulated glass and solves the problem of traditional insulated glass not being tightly sealed, which leads to air and moisture entering the air gap, causing inert gas leakage and reducing heat and sound insulation performance.

[0009] 2) A type of sealed, filled insulating glass as described in 1), wherein:

[0010] The side of the silicone block facing away from the spacer strip and the sides of the two glass plates are covered with a silicone base coating.

[0011] In this invention, the silicone base coating can improve the bonding performance between the silicone sealant block and the glass plate, making the connection between the silicone sealant block and the glass plate more secure, improving the overall structural strength of the insulating glass, and preventing the silicone sealant block from falling off or the seal from failing during long-term use due to poor bonding between the silicone sealant block and the glass plate, thereby improving the quality and service life of the insulating glass.

[0012] In addition, the silicone undercoat can form a dense protective film on the side of the glass, blocking direct contact between external corrosive substances and the glass and silicone sealant. It also avoids corrosion caused by electrochemical reactions between different materials, ensuring that the insulated glass is in a stable working state for a long time, reducing the erosion of the two glass panels and silicone sealant blocks by external corrosive media, preventing the side of the glass panels from being corroded and affecting their performance, and preventing the silicone sealant blocks from cracking and hardening due to corrosion, thus extending the service life of the insulated glass.

[0013] 3) A type of sealed, filled insulating glass as described in 1), wherein:

[0014] The width of the spacer strip is equal to the distance between the two glass plates, and the two ends of the spacer strip are respectively bonded to the inner surfaces of the two glass plates with butyl adhesive.

[0015] In this invention, a long strip-shaped spacer is placed in the gap between the edges of the two glass plates. The two ends of the spacer are bonded to the two glass plates with butyl adhesive. The spacer separates the two glass plates, forming a gap of a certain width, so that the insulated glass has good sound insulation and heat insulation performance. In addition, the spacer can ensure that the gap thickness between the two glass plates is uniform and consistent, and prevent the two glass plates from contacting each other, so as to ensure the structural stability and performance reliability of the insulated glass.

[0016] When used in conjunction with butyl sealant, spacers effectively prevent external air and moisture from entering the hollow layer formed between the two glass panes, maintaining the dryness and gas stability within the hollow layer, extending the service life of the insulated glass, and preserving its heat insulation and sound insulation performance. In addition, they also play a role in buffering and shock absorption to a certain extent, reducing damage to the glass caused by thermal expansion and contraction or external vibrations, and improving the impact resistance of the insulated glass.

[0017] 4) A type of airtight insulated glass according to 3), wherein:

[0018] The spacer strip is connected to a silicone block at its bottom. The spacer strip has an opening in the middle of the silicone block. The silicone block has a protrusion that matches the opening in the direction of the spacer strip. The protrusion is fixedly connected to the opening. The spacer strip and the silicone block form an I-shaped connection structure.

[0019] In this invention, compared to planar bonding, the embedded connection of protrusions and openings significantly increases the contact area and mechanical interlocking force between the spacer and the silicone block, thereby enhancing the firmness of the connection between the spacer and the silicone block. This makes it less likely for the connection to separate when the insulating glass is subjected to external impact, vibration, or deformation due to temperature changes, thus ensuring the overall structural stability of the insulating glass.

[0020] The protruding, embedded opening structure reduces gaps at the connection points. Combined with sealing materials such as butyl sealant, it further enhances the sealing performance of the insulating glass edges, preventing external moisture and air from seeping into the gap between the two glass panes through the connection points. This better maintains the filling effect of the inert gas, ensuring the heat insulation and sound insulation performance of the insulating glass. In addition, the matching design of the protrusion and opening allows for precise positioning during installation, making it easy for operators to quickly and accurately connect the silicone sealant block to the spacer strip, thus improving installation efficiency.

[0021] In addition, the I-beam connection structure can more evenly distribute external forces. When the insulated glass is subjected to external forces, these forces can be more effectively transferred between the spacer and the silicone sealant through the I-beam structure, avoiding localized stress concentration, reducing the risk of component damage, and extending the service life of the insulated glass.

[0022] 5) A type of sealed, filled insulating glass according to 1), wherein:

[0023] The I-shaped connecting structure has a space between it and the two glass plates to accommodate butyl sealant. The silicone sealant block, the spacer strip, the butyl sealant, and the two glass plates form an integrally connected structure.

[0024] In this invention, the integrated connection structure tightly binds the silicone sealant block, spacer strip, butyl sealant, and glass plate into a whole. The different materials work together to bear the force. When subjected to external impact, wind pressure changes, or temperature stress, the overall structure can jointly bear the force, reducing the risk of local damage and enhancing the deformation and damage resistance of the insulating glass. The integrated connection structure tightly binds the components, solving the problem of loose structure and improving the structural reliability of the insulating glass.

[0025] In addition, butyl sealant fills the specific space to form a continuous and complete sealing layer, which effectively fills the tiny gaps between the I-shaped structure and the glass panel, further preventing outside air and moisture from entering the insulated layer, ensuring the retention rate of inert gas, and improving the heat insulation and sound insulation performance of the insulated glass. Good sealing can avoid problems such as condensation and oxidation in the gap between the two glass panels, prevent glass edge corrosion and sealant aging, and the integrated structure ensures the long-term stability of the connection between the components, reducing the possibility of performance degradation due to loose connections, thereby extending the service life of the insulated glass.

[0026] Compared with the prior art, the present invention has the following technical advantages:

[0027] In this invention, butyl adhesive is used to bond the spacer strip, silicone sealant block, and glass plate separately, while filling the gap between the silicone sealant block and the spacer strip to form a multi-layer sealing structure. This greatly reduces the possibility of external air and moisture entering the insulating layer, ensuring that the inert gas is not easily leaked and effectively maintaining the sealing state of the insulating glass.

[0028] Meanwhile, the inert gas filling the gaps between the glass panes has a low thermal conductivity that can significantly reduce heat conduction and enhance thermal insulation performance. After the inert gas is filled inside the insulated glass, the internal pressure of the insulated glass is more stable, which can reduce the pressure difference between the inside and outside of the glass caused by factors such as temperature changes, thereby reducing the possibility of spontaneous breakage of the insulated glass. The multiple sealing structure combined with the inert gas can effectively block the transmission of sound, improve the sound insulation effect, and create a comfortable and quiet indoor environment.

[0029] Furthermore, the spacer strip, silicone sealant blocks, and glass panels are firmly bonded together with butyl adhesive, working in tandem to enhance the overall structural stability of the insulated glass unit and improve its resistance to environmental interference. This makes the insulated glass less prone to deformation and cracking when subjected to external wind pressure, temperature changes, and other factors. Attached Figure Description

[0030] Figure 1 This is a cross-sectional view of a sealing-filled insulated glass unit according to an embodiment of the present invention. Detailed Implementation

[0031] The following detailed description illustrates the specific implementation method:

[0032] The reference numerals in the accompanying drawings include: glass plate 1, spacer strip 2, butyl rubber 3, silicone rubber block 4, silicone primer 5, opening 6, protrusion 7, inert gas 8.

[0033] Reference will now be made in detail to the embodiments disclosed herein. Although the disclosure will be described in conjunction with embodiments and / or examples, they are not intended to limit the disclosure to these embodiments and / or examples. Rather, the disclosure covers alternatives, modifications, and equivalents.

[0034] See the example. Figure 1 As shown, this embodiment is a sealed insulated glass unit, including two glass plates 1 with a certain gap between them. The gap is filled with inert gas 8. A long strip spacer 2 is provided on the edge of the two glass plates 1 and located in the gap. The two ends of the spacer 2 are respectively bonded to the two glass plates 1 by butyl adhesive 3. A silicone block 4 is connected to the side of the spacer 2 away from the inert gas 8. The two ends of the silicone block 4 are bonded to the two glass plates 1 by butyl adhesive 3. There is a gap filled with butyl adhesive 3 between the silicone block 4 and the spacer 2.

[0035] In this invention, the two glass plates 1 are made of the same material and have the same size. The two glass plates 1 are arranged in parallel and their edges are aligned to form a gap in the middle. The gap is filled with an inert gas 8, which is argon. The inert gas 8 has low thermal conductivity, which can effectively prevent heat from passing through the glass, reduce the heat exchange between the indoor and outdoor areas, and keep the indoor and outdoor temperatures relatively stable. In addition, the inert gas 8 can block the transmission of sound to a certain extent, thereby improving the sound insulation performance of the insulated glass. After the inert gas 8 is filled inside the insulated glass, its internal pressure is more stable, which can reduce the pressure difference between the inside and outside of the glass caused by factors such as temperature changes, thereby reducing the possibility of spontaneous breakage of the insulated glass.

[0036] Butyl sealant 3 has excellent airtightness and watertightness. By bonding the spacer strip 2, silicone sealant block 4 and the two glass plates 1 with butyl sealant 3, and filling the gap between silicone sealant block 4 and spacer strip 2, a multi-layer sealing structure is formed. This greatly reduces the possibility of external air and water vapor entering the gap formed by the two glass plates 1, ensuring that the inert gas 8 is not easily leaked, effectively maintaining the sealing state of the insulating glass, and effectively solving the defect of traditional insulating glass that is not tightly sealed, which leads to air and water vapor entering the insulating layer, causing the inert gas 8 to leak and reducing the heat insulation and sound insulation performance.

[0037] A silicone base coating 5 is applied to the side of the silicone block 4 away from the spacer strip 2 and the sides of the two glass plates 1.

[0038] In this invention, the silicone base coating 5 can improve the bonding performance between the silicone sealant block 4 and the glass plate 1, making the connection between the silicone sealant block and the glass plate 1 more secure, improving the overall structural strength of the insulating glass, and preventing the silicone sealant block 4 from not being tightly bonded to the glass plate 1, which could lead to the sealant block falling off or the seal failing during long-term use, thus improving the quality and service life of the insulating glass.

[0039] In addition, the silicone base coating 5 can form a dense protective film on the side of the glass plate 1, blocking the direct contact between external corrosive substances and the glass and silicone sealant, while avoiding corrosion caused by electrochemical action between different materials, ensuring that the insulating glass is in a stable working state for a long time, reducing the erosion of the two glass plates 1 and silicone sealant block 4 by external corrosive media, preventing the surface of the glass plate 1 from being corroded and affecting its performance, and preventing the silicone sealant block 4 from cracking and hardening due to corrosion, thus extending the service life of the insulating glass.

[0040] The width of the spacer 2 is equal to the distance between the two glass plates 1, and the two ends of the spacer 2 are respectively bonded to the inner surfaces of the two glass plates 1 by butyl adhesive 3.

[0041] In this invention, a long strip-shaped spacer 2 is disposed in the gap between the edges of the two glass plates 1. The two ends of the spacer 2 are respectively bonded to the two glass plates 1 with butyl adhesive 3. The spacer 2 separates the two glass plates 1, forming a gap of a certain width, so that the insulated glass has good sound insulation and heat insulation performance. In addition, the spacer 2 can ensure that the gap thickness between the two glass plates 1 is uniform and consistent, and prevent the two glass plates 1 from contacting each other, so as to ensure the structural stability and performance reliability of the insulated glass.

[0042] The spacer 2, used in conjunction with butyl rubber 3, can effectively prevent external air and moisture from entering the hollow layer formed by the gap between the two glass plates 1, maintain the dryness and gas stability within the hollow layer, extend the service life of the insulating glass, maintain its heat insulation and sound insulation performance, and also play a certain role in buffering and shock absorption, reducing damage to the glass caused by thermal expansion and contraction or external vibrations, and improving the impact resistance of the insulating glass.

[0043] The bottom of the spacer 2 is connected to a silicone block 4. The spacer 2 has an opening 6 in the middle of the silicone block 4. The silicone block 4 has a protrusion 7 that matches the opening 6 in the spacer 2. The protrusion 7 is fixedly connected to the opening 6. The spacer 2 and the silicone block 4 form an I-shaped connection structure.

[0044] In this invention, compared to planar bonding, the embedded connection between the protrusion 7 and the opening 6 significantly increases the contact area and mechanical interlocking force between the spacer 2 and the silicone block 4, thereby improving the firmness of the connection between the spacer 2 and the silicone block 4. This makes it less likely for the connection to separate when the insulating glass is subjected to external impact, vibration, or deformation due to temperature changes, thus ensuring the overall structural stability of the insulating glass.

[0045] The structure of the protrusion 7 embedded in the opening 6 reduces the gaps at the connection point. Combined with sealing materials such as butyl sealant 3, it further improves the sealing performance of the edge of the insulating glass, preventing external moisture and air from seeping into the gap between the two glass panels 1 through the connection point. This better maintains the filling effect of the inert gas 8, ensuring the heat insulation and sound insulation performance of the insulating glass. In addition, the matching design of the protrusion 7 and the opening 6 can play a role in precise positioning during installation, making it convenient for operators to quickly and accurately connect the silicone sealant block 4 to the spacer strip 2, thus improving installation efficiency.

[0046] In addition, the I-beam connection structure can more evenly distribute external forces. When the insulated glass is subjected to external forces, these forces can be more effectively transferred between the spacer 2 and the silicone sealant block 4 through the I-beam structure, avoiding localized stress concentration, reducing the risk of component damage, and extending the service life of the insulated glass.

[0047] The I-shaped connecting structure has a space between the two glass plates 1 to accommodate butyl sealant 3. The silicone sealant block 4, the spacer strip 2, the butyl sealant 3, and the two glass plates 1 form an integrally connected structure.

[0048] In this invention, the integrated connection structure tightly binds the silicone sealant block 4, spacer strip 2, butyl sealant 3, and glass plate 1 into a whole. The different materials work together to bear the force. When subjected to external impact, wind pressure changes, or temperature stress, the overall structure can jointly bear the force, reduce the risk of local damage, and enhance the deformation resistance and damage resistance of the insulating glass. The integrated connection structure tightly binds the components, solves the problem of loose structure, and improves the structural reliability of the insulating glass.

[0049] In addition, butyl sealant 3 fills the specific space to form a continuous and complete sealing layer, which effectively fills the tiny gaps between the I-shaped structure and the glass plate 1, further preventing external air and moisture from entering the insulating layer, ensuring the retention rate of inert gas 8, and improving the heat insulation and sound insulation performance of the insulating glass. Good sealing can avoid problems such as condensation and oxidation in the gap between the two glass plates 1, prevent glass edge corrosion and sealant aging, and the integrated structure ensures the long-term stability of the connection between the components, reducing the possibility of performance degradation due to loose connection, thereby extending the service life of the insulating glass.
